Zurich, Switzerland, January 15, 2008 -- Molecular Partners AG today announced a collaborative research and license agreement with Centocor Research & Development, Inc. The collaboration will focus on the development of DARPins (Designed Ankyrin Repeat Proteins), a novel class of therapeutic proteins to treat inflammatory diseases. Under the collaboration, Molecular Partners will apply its proprietary DARPin technology for the identification of DARPins to two undisclosed targets. Centocor will perform the preclinical and clinical development as well as commercialization of resulting products.

Molecular Partners will receive an upfront payment of $5 million, additional research funding and license fees.
